GitHub Light Navbar

Brings back the old navbar on github.com. Only works when you are logged in!
Update: After the search field update, I now have to include a few lines of javascript code to make it expand when focused.
Extra features:
- The search field will expand when focused.
- You can resize textareas to larger than 500px in height.
